Main Technical Features
● PressurMain Technical Featuresized components are forged materials, having good strength
and impact toughness, avoid the forging default.
● Middle flange uses combined seal, its switch is operated by hydraulic pressure, easy to change
the ram.
● Equipped with auxiliary oil cylinder, compared with the traditional shear ram BOP, it has the
function, smaller volume.
● Ram rubber is abundant, and use self-contained seal.
● Manual locking device belongs to the standard configuration, In the event of hydraulic loss, it
can ensure that ram remains closed.
● Manual and hydraulic locking device and auxiliary oil cylinder can be equipped according to
customer's requirements flexibly, and easy to interchange.
● The internal shell of BOP resistant to low temperature can process pipeline, to make the
steam flow inside the BOP, radiat heat. (for costumer’s option).
● The internal part of BOP resistant to high sulfur which contact the well liquid has Surfaced
high nickel base alloy, which can achieve the highest levels of resistance to H2S and CO2.
● Manufactured in accordance with API Specification 16A, and NACE MR0175
